Comparative Study Parallel Join Algorithms for MapReduce environment
Alice Pigul · Proceedings of the Institute for System Programming of RAS · 2012
There are the following techniques that are used to analyze massive amounts of data: MapReduce paradigm, parallel DBMSs, column-wise store, and various combinations of these approaches. We focus in a MapReduce environment. Unfortunately, join algorithms is not directly supported in MapReduce. The aim of this work is to generalize and compare existing equi-join algorithms with some optimization techniques.
